signals and events

What is the state of signals and events support? As far as I can tell from
watching which perl 5 regression tests fail or hang under parrot, currently
parrot can't behave as a passive embedding target - it assumes that it needs
to take ownership of all signals.

Is this likely to change soon? Currently ponie has had to add various skip
blocks to perl 5 regression tests that throw/catch signals, and this doesn't
seem ideal as it implies that code changes would also be needed by existing
CPAN code to work properly under ponie.
